Abstract

Industry 4.0 (I4) as a concept offers powerful opportunities for many businesses. The set of Industry 4.0 technologies is still discussed, and boundaries are not perfectly clear. However, implementation of Industry 4.0 concept becomes strategic principle, and necessary condition for succeeding on turbulent markets. Radio Frequency Identification (RFID) was used before I4 emerged. However, it should be treated as its important part and even enabler. The question arises how adoption of RFID was impacted by I4 paradigm. Therefore, to answer this question a set of technology management tools was selected and applied to forecast RFID potential development in forthcoming years. Moreover, case studies were conducted for technology management tools and their applications for RFID for qualitative discussion of its relevance. It aimed to prove that existing toolset should be applied for modern technologies related to I4. Tools were proven to be necessary and successful. However, some specific challenges were observed and discussed.

Abstract

Commercialization processes are modeled and analyzed from the point of view of the implementation of activities under particular stages. These issues are the subject of many studies and analyzes, which is why the extensive literature is available on this subject. Technology valuation at various stages of the commercialization process is a separate issue. Such valuation is prepared in most cases by consulting companies for determining the price in the buying and selling processes. These valuations use known methods also used in other cases, e.g., real estate valuation. The work carried out presents the author’s concept of the commercialization process model, taking into account the costs and value of the technology at various stages of the product life cycle. The model uses a stochastic approach to determine future revenues and costs, which allows estimating the value of the technology by or in determining the probability of assessment validity. The proposed stochastic approach greatly increases the chances of using the presented solutions in practical activities related to technology valuation for the purposes of purchase and sale transactions.

Abstract

Industry 4.0 promises to make manufacturing processes more efficient using modern technologies like cyber-physical systems, internet of things, cloud computing and big data analytics. Lean Management (LM) is one of the most widely applied business strategies in recent decades. Thus, implementing Industry 4.0 mostly means integrating technologies in companies that already operate according to LM. However, due to the novelty of the topic, research on how LM and Industry 4.0 can be integrated is still under development. This paper explores the synergic relationship between these two domains by identifying six examples of real cases that address LM-Industry 4.0 integration in the extant literature. The goal is to make explicit the best practices that are being implemented by six distinct industrial sectors

Abstract

In the authors’ opinion, the issue of incorrectly functioning water insulation of foundation walls in the existing buildings in Poland is currently rather common. The paper includes a multicriteria analysis aimed at arranging the selected options of the foundation wall vertical water insulation technology in an existing model historic building using the weighted sum, entropy and AHP methods. Each of the studied solutions was evaluated in terms of the following criteria: costs of construction works, time of execution of construction works, popularity of using particular insulation options by other contractors, durability of the executed insulation and the degree of nuisance of the executed works

Abstract

In the paper the topic of Building Information Technology BIM is investigated. It is new in Polish circumstances technology for construction and for building product industry, which contribute to change and develop level of industrialization. Especially challenge raising from the information and introducing IT technology into daily practice is considered to provide changes in construction branch of economy. In Poland there is the hot need of start to introduce BIM as the common technology for owners of assets, facility management, construction entities, design offices, administration officers and many other players relative to construction data and processes. BIM technology introduction, basing on foreign case studies, results in cost savings, control and time reduction of investment processes and some more advantages. The perspective of digital buildings, digital infrastructure, digital roads, digital railways and digital cities is outlined at the perspective of technology challenge, but simply transfiguration of many fields of personal everyday life, where digitalization is already present and with the question when it will be common in professional activity, particularly in civil engineering.

Abstract

Article deals with the problem of technology selection for construction project. Three criteria were proposed: cost, time and technological complexity. To solve the problem, fuzzy preference relations were used. Authors present an algorithm supporting multi-criteria decision-making process. The algorithm creates fuzzy preference relations on the basis of the fuzzy comparison: “xᵢ is better than xj”.Then, with the use of criteria weights it creates general fuzzy preference relation, finds all non-dominated (admissible) alternatives and the best one among them. The algorithm consists of 7 steps. Authors show application of the proposed algorithm – example calculations.

Abstract

Stanisław Lem is mostly known as a sci-fi writer and not widely perceived as a visionary of the cyber age, despite the fact that he foresaw the future of information technology better than most scientific experts. Indeed, his visions of future information- based societies have proved to be remarkably accurate. Lem’s stories fuse together elements of fantasy, philosophy, and science, but what we can really learn from them is the nature of humanity, technology, and philosophy, as well as the values of technological prophecies. Moreover, Lem gave birth to, without naming it as such, the concept of philosophy in technology, which is a perspective on technology and philosophy that explores the deep implicit philosophical foundations of technology and humanity.

Abstract

One of the basic requirements of the paradigm of sustainable architecture is the use of materials and building systems characterized by low embodied energy. The aim of this paper is to examine the problem of rational design for lower embodied energy of building components and details. To raise the suitable competence of building professionals and stakeholders, the paper recommends some ways of approach to these issues. The reduction in the quantity of applied materials, so called dematerialization, the use of low energy materials for construction, reduced maintenance works, less frequent exchange of components and materials during the building operation, and their higher durability lead to better results in this regard. Some exemplary practical applications of such approach to design of contemporary buildings using the state-of-the art technologies, which strive to be in line with the requirements for sustainability, as well as some other being contradictory to them, have been covered in this paper.

Abstract

This study aims to design a novel air cleaning facility which conforms to the current situation in China, and moreover can satisfy our demand on air purification under the condition of poor air quality, as well as discuss the development means of a prototype product. Air conditions in the operating room of a hospital were measured as the research subject of this study. First, a suitable turbulence model and boundary conditions were selected and computational fluid dynamics (CFD) software was used to simulate indoor air distribution. The analysis and comparison of the simulation results suggested that increasing the area of air supply outlets and the number of return air inlets would not only increase the area of unidirectional flow region in main flow region, but also avoid an indoor vortex and turbulivity of the operating area. Based on the summary of heat and humidity management methods, the system operation mode and relevant parameter technologies as well as the characteristics of the thermal-humidity load of the operating room were analyzed and compiled. According to the load value and parameters of indoor design obtained after our calculations, the airflow distribution of purifying the air-conditioning system in a clean operating room was designed and checked. The research results suggested that the application of a secondary return air system in the summer could reduce energy consumption and be consistent with the concept of primary humidity control. This study analyzed the feasibility and energy conservation properties of cleaning air-conditioning technology in operating rooms, proposed some solutions to the problem, and performed a feasible simulation, which provides a reference for practical engineering.

Abstract

This polemic discusses two problematic aspects to the claim of a paradigmatic shift to the new technology-centered symbolic universe, as understood by Peter Berger and Thomas Luckmann.
The first problematic aspect is connected to the status quo ante transhumanism (before the postulated paradigmatic shift). By discussing cases from pre-modernity and peak modernity, I point out that the discussed claim does not provide satisfactory understanding of the role of technology in society. My counter-argument is built on cases of technoreligious institutions such as abbeys and rocketry research theoretical circles, using works by David Noble as the starting point.
The second problematic aspect goes back to the fundamentals of Berger and Luckmann’s concept and its relation to ontology. The discussed proposal mixed this framework with the concept of culture from the Margaret Archer system, which led to a shift in ontological positioning. In effect, some preliminaries about the materiality and dynamics of Berger-Luckmann dialectics are harder to trace in the proposal. This results in problems of operationalization and loss of useful theoretical dialogue with post-constructivist tradition.
In the last part of the paper, I sketch other possibilities and challenges for post Berger-Luckman applications in the case of transhumanism and late modernity.

Abstract

Thaddeus Bulgarin (1789–1859) – a writer, critic and publishеr. During his activity hеtried to find his place in the history of both Polish and Russian literature and culture. However, neither Poles nor Russian considered him as their national author, despite the fact he was a very popular figure in the first half of the 19th century. Although Bulgarin’s heritage consists of numerous writings in the field of science-fiction literature, his name cannot be аlsо found among its creators. This article analyses the most significant visions of future by Bulgarin, in particular regarding the development of technology and its impact on human beings. Then it could be said that it was not Julius Verne, but Thaddeus Bulgarin, was the first one toprovide readers with travels to the centre of the Earth.

Abstract

Traffic related noise is currently considered as an environmental pollution. Paper presents results of multidirectional study attempting to serve urban traffic without the need to erect noise barriers interfering urban space. Initial concept of the road expansion included construction of 1000 m of noise barriers dividing city space. Improvement in the acoustic conditions after construction completion is possible due to the applied noise protection measures: vehicle speed limit, smooth of traffic flow, use of road pavement of reduced noise emission and the technical improvement of the tramway.

Abstract

This paper considers modern production technologies of solid biofuels from the point of view of compliance with labor protection and environmental safety measures. The relevance of the study lies in the fact that environmental safety, in our opinion, supported by the results of the analysis of literature sources and their research, covers almost all residential areas of the community. The purpose of this scientific research is to develop theoretical foundations and practical management solutions to ensure environmental safety when producing solid biofuels. Thematic works of domestic and foreign specialists form the theoretical and methodological basis of the research. The following methods of scientific research were used as objective methods: logical analysis of knowledge, scientific generalization, deduction and analogies. The practical significance of the obtained results lies in the application of established models and emergency situations as well as environmental safety in practice. An environmental safety system was developed that regulates the state in its natural conditions based on established production control models for solid biofuels. The article presents recommendations for students of higher educational institutions (technical areas) to study materials on labor protection and the environmental safety of our time.

Abstract

In the first part of the paper the most often used processes in PRB technology are presented and described. These processes are: redox reactions, pH control, adsorption and biodegradation. They proceed in the reactive materials listed in the table. In the second part of the paper the procedure used in the assessment of possibilities of using PRB technology is presented. It was suggested to use preliminary assessment during the initial stage of the procedure, as it limits the range of the analysis to several most important factors. Moreover,. the conditions of using PRB were described. They can help to decide whether this technology should be accepted or not in the initial stage of the procedure. Such preliminary assessment of possibilities of using PRB was performed for two selected areas of dumping sites located in Upper Silesia, Poland. After accepting the possibilities of using this technology in their area, the types of reactive materials for effective treatment of groundwater were proposed for both of them.

Abstract

The paper presents results of a simulation of the plasmon effect achieved between a thin precious metal layer and a biconical optical fibre taper, manufactured on a standard single mode fibre. Gold, silver and titanium were used as a metal which fulfilled a cladding function for a small diameter structure. For simulation Mode Solution software was used on which modal and frequency analyses of a wavelength were provided in the range of 800–1700 nm. A displacement of a plasmon pick in dependence of thickness of a deposited precious layer for the highest plasmon effects was observed.

Abstract

To comprehensively investigate the diversity of a chamfer technology and a convex roll technology under the same soft reduction process (i.e., section size, reduction amount, casting speed and solid fraction), a three-dimensional mechanical model was developed to investigate the effect of the chamfer profile and roll surface profile on the deformation behavior, cracking risk, stress concentration and reduction force of as-cast bloom during the soft reduction process. It was found that a chamfer bloom and a convex roll can both avoid the thicker corner of the as-cast bloom solidified shell, and significantly reduce reduction force of the withdrawal and straightening units. The convex profile of roll limits lateral spread along bloom width direction, therefore it forms a greater deformation to the mushy zone of as-cast bloom along the casting direction, the tensile strain in the brittleness temperature range (BTR) can obviously increase to form internal cracks. The chamfer bloom is much more effective in compensating the solidification shrinkage of mushy zone. In addition, chamfer bloom has a significant decrease of tensile strain in the brittleness temperature range (BTR) areas, which is expected to greatly reduce the risk of internal cracks.

Abstract

There are two methods to produce primary copper: hydrometallurgical and pyrometallurgical. Copper concentrates, from which copper

matte is melted, constitute the charge at melting primary copper in the pyrometallurgical process. This process consists of a few stages, of

which the basic ones are roasting and smelting. Smelting process may be bath and flash. Slag from copper production, on the end of

process contain less 0,8%. It is treat as a waste or used other field, but only in a few friction. The slag amount for waste management or

storage equaled 11 741 – 16 011 million tons in 2011. This is a serious ecological problem. The following slags were investigated: slag

originated from the primary copper production process in the flash furnace of the Outtokumpuja Company in HM Głogów 2 (Sample S2):

the same slag after the copper removal performed according the up to now technology (Sample S1): slag originated from the primary

copper production process in the flash furnace of the Outtokumpuja Company in HM Głogów 2, after the copper removal performed

according the new technology (Sample S3). In practice, all tested slags satisfy the allowance criteria of storing on the dumping grounds of

wastes other than hazardous and neutral.

Abstract

The paper presents the results of investigation into the technological possibility of making light-section castings of GX2CrNiMoN25-6-3

cast steel. For making castings with a wall thickness in the thinnest place as small as below 1 mm, the centrifugal casting technology was

employed. The technology under consideration enables items with high surface quality to be obtained, while providing a reduced

consumption of the charge materials and, as a result, a reduction in the costs of unit casting production.
